The proliferation of Regional Trade Agreements (RTAs) notified to the GATT/WTO since the early 1980s deviates from the long-term trend and reflects participation of nearly every member of the United Nations. This dissertation seeks to explain the current wave of RTA notifications by supplementing the economic model of supply and demand with diffusion theory. Application of the supply and demand model is useful in distinguishing between changes in demand and changes insupply of RTAs. This distinction is seldom emphasized in the current literature examining RTAs. Recent applications of diffusion theory in the discipline of international relations offer a unique opportunity to include a dynamic force in the static analysis of the supply and demand model. Empirical analysis assesses the fit of the RTA diffusion pattern by comparing the RTA diffusion pattern to a cumulative standard normal distribution. The analysis indicates that the diffusion pattern of RTAs resembles the diffusion of an innovation through a social system.; The implication of this finding is that the adoption of an RTA as trade policy is not made independently of the decision by other states. Indeed, the analysis suggests interdependency between states. Further empirical analysis explores economic and political variables that may explain the decision to adopt the RTA as trade policy. The empirical analysis is unique in that survival analysis is utilized to assess the variation in duration to adopt an initial RTA since the early 1980s. A central discovery is that regional designation explains the variation in duration to adopt an initial RTA. Multiple regression analysis confirms the results generated using survival analysis and support the assertion that the proliferation of RTAs likely reflects changes in both the demand for RTAs and the supply of RTAs. This dissertation concludes by considering implications for the WTO resulting from the increase in RTA notifications.
